Etrigan

 

Demon

Etrigan first appeared in The Demon #1 (September 1972) and was created by Jack Kirby. He created him at the behest of DC, who saw it as likely to be more commercially successful than the Fourth World and thus cancelled New Gods and Forever People to facilitate his working on the new title. According to Mark Evanier, Kirby had no interest in horror comics, but created Etrigan in response to a demand from DC for a horror character. Kirby was annoyed that the first issue sold so well that DC required him to do sixteen issues and abandon the Fourth World titles before he was done with them.
